Oh, This is I have found a programSo fast, and so cool. But ahm, I feel uncomfortable to click left button continuosly while for watching 100% fit.It is reallly tired. Because I much spent time watching 100% fit than any small.I hope this program has a invert option. It means image 100% fit on start.And When I click to left button I can see whole image.I sure this function is very helpful.
